Second Derivative Photoplethysmography Implementation
ثبت نشده
چکیده
Photoplethysmography (PPG) provides an estimation of blood flow by measuring the dynamic attenuation of visual or infrared light by the blood volume present in tissue. The contour of the pulsatile component of the PPG signal has been found to include content descriptive of vascular health. PPG pulse signals can be easily obtained from the tissue pads of the ears, fingers and toes where there is a high degree of superficial vasculature. The noninvasive assessment of cardiovascular function by means of the peripheral arterial pulse has gained substantial interest in recent years due to the integration of sensor technology and the ubiquitous application of microprocessors. APMKorea developed DCM01, 02, 03 integrated dual emitters and a detector in single substrate which work reflectively.

Nordsieck representation of high order predictor-corrector Obreshkov methods and their implementation
Predictor-corrector (PC) methods for the numerical solution of stiff ODEs can be extended to include the second derivative of the solution. In this paper, we consider second derivative PC methods with the three-step second derivative Adams-Bashforth as predictor and two-step second derivative Adams-Moulton as corrector which both methods have order six. Implementation of the proposed PC method ...

Ancient Indian Ayurveda has used the palpation of the pulse at the wrist under the thumb to analyze physical health. In the nineteenth century, analysis of the contour of the peripheral pulse to assess arterial properties was first described. With the recognition of the importance of arterial stiffness there has been a resurrection of interest in pulse wave analysis. The non-invasive evaluation...
متن کاملEstimation of biophysical and functional properties of artery walls from pulse wave measured by photoplethysmography
Arterial pulse wave analysis in time and frequency domain was carried out to find out biophysical and functional properties of artery walls measured with a photoplethysmographic (PPG) device. Because peripheral arterial disease (PAD) is a fatal problem all over the world, an easy diagnosis method would be needed. It could probably be diagnosed by PPG which is a non-invasive optical technique fo...

It is well-known that the electrocardiogram (ECG) is a non-invasive method that can be used to measure heart rate variability (HRV). Photoplethysmogram (PPG) signals also reflect the cardiac rhythm since the mechanical activity of the heart is coupled to its electrical activity. Photoplethysmography is a non-invasive, safe, and easy-to-use technique that has been developed for experimental use ...
